The first time i got my LCD, i wired it into my computer for the power source because i didn't have an AC adapter. Well, i accidently wired it to the 5V+ and the monitor was all jacked up.. like it looked it was the wrong frequency. I caught the error and put it to the other wire and it worked fine. It's most likely ure power input

Might be a stupid idea. but could it be heat? I know when I mounted Mine there wasnt very much breathing room and after about 5mins I'd get a 'similar' thing happening. Im asuming that you have tryed the unit unmounted or are trying it this way.

Cheers,
Mik.

The box said Windows 9x or better.. so I installed Linux
